Abstract

The invention discloses a dynamic human body three-dimensional reconstruction method, device and equipment and a medium, and relates to the technical fields of computer vision, computer graphics, three-dimensional reconstruction, virtual reality, augmented reality and the like. According to the specific implementation scheme, a human body three-dimensional model is reconstructed according to an RGB image and a depth image, collected based on a single view angle, of a target human body; posture estimation is performed on the target human body according to the RGB image; according to the estimated corresponding relation between the two-dimensional posture and the human body three-dimensional model and the estimated corresponding relation between the three-dimensional posture and the human body three-dimensional model, bone movement and non-rigid movement of the human body three-dimensional model are estimated, and therefore the robustness of dynamic human body three-dimensional reconstruction based on a single view angle is improved. The voxel fusion is performed on the human body three-dimensional model after movement according to the matching result of the semantic information of the target node before and after movement, so that the fusion of the wrong human body surface is avoided.

Description

technical field [0001] Embodiments of the present invention relate to technical fields such as computer vision, computer graphics, three-dimensional reconstruction, virtual reality, and augmented reality. In particular, it relates to a dynamic human three-dimensional reconstruction method, device, equipment and medium. Background technique [0002] In computer vision and computer graphics, reconstruction has been an important research problem in both disciplines, ranging from reconstruction of static scenes, rendering problems to tracking and surface reconstruction of moving objects (especially people). [0003] Although the current single-view reconstruction equipment is simple, it limits the complexity and speed of reconstructing human motion to a certain extent. How to improve the robustness of 3D reconstruction of dynamic human body based on single view has become one of the problems to be solved urgently in this field.
